A display device includes: an acquisition unit which acquires a first image from an image supply device; a detection unit which specifies a position of the indicator and whether the indicator is a first indicator or a second indicator; a generation unit which generates a second image based on the specified position and generates a third image by superimposing the second image on the first image; a display unit which displays the third image; a designation unit which designates either the generation unit or the image supply device as a supply destination of information indicating a position of the second indicator; and a control unit which supplies the information indicating the position of the indicator to the generation unit if the detected indicator is the first indicator, and supplies the information indicating the position of the indicator to the supply destination if the detected indicator is the second indicator.
